Extractor Manifold - MGB V8 RoadSport Type

Improving the gas flow through the engine is the key to gaining more power, a simple first step 'Stage 1' is to upgrade the induction & exhaust.

Fitting an extractor manifold with a performance exhaust allows the engine to breathe more easily. To gain the most benefit, our extractor manifolds and performance exhaust systems should be used together.

Extractor Manifolds work by allowing the gasses to flow through a smoother path and the large bore pipes reduce back-pressure in the manifold & cylinder head. Additional power can be gained by wrapping the manifold, this keeps the exhaust gasses hot which means they have less density and flow more freely. It also reduces the heat within the engine bay which gives a cooler induction charge, increasing the air density.

Our manifolds and systems are manufactured to the highest standards and are available in high quality mild steel or type 304 stainless steel. All pipes are mandrel bent to maintain tube shape and assembly is done on jigs to ensure accuracy and quality fit.

Our tubular extractor manifold for the MGB V8 has been designed to get the maximum gas flow from the limited space in the engine bay. This 5 piece manifold is specifically designed for all Roadster & GT V8s, with standard engine bays, and works well with engines up to 200bhp.

The manifold is designed for use with the Moss V8 Sports Exhaust System - MGS51020 but can be used with Falcon MGB GT V8 Exhaust Systems by using the link pipe BHH1000CX between manifold Y piece and the exhaust system. Manifold set includes RH and LH manifolds, down pipes and Y piece.

If greater power output is required we recommend using the RV8 type of manifold. This has longer primary pipes which pass through the inner wings.
